what size belt with an s-trim???

[88mustng]

i got a vortech s-trim and its all on, says to use a stock size belt but when i got one and put it on, if i have it around all the other pulleys i can only get it about half way around the the ac compressor, what size belt do you guys use when you put the s-trim on????

you might have to lossen the alternator and put the belt on and then pry the alternator back into position to get the bolt in...it will make the belt really tight so it doesnt slip also.

I run a belt that is 1" longer than stock. Fits perfectly with my 3g alternator that has a bigger pulley in diameter than the stock alternator.
